Can you pre-mix your saltwater in a 30 or 50 gallon can and keep it to use as needed? What are some other alternatives to use besides buying bottled water and not using tap water? Could you use tap water if you have a filter on the faucet? I want to have a 200-300 gallon shark tank and am trying to make sure I have everything I need before starting to make it easier. I'm a long way off but am trying to learn as much as I can.
